what is the simplest definition of ion exchange capacity

What this unit identifies for the ion exchange capacity ca. 0.92 meq. g-1. I am a newcomer in the membrane area. I just started. I highly appreciate your help

I think a recent paper attached here may be helpful for your question.

Although several years have been passed since their publication, the list of papers provided by Carina Moeller (above) still very applicable to dry-land agriculture. I am well aware of the work of McNeill et al. research team, one of the leading research team on dry-land agriculture . I believe, they still have a very active research program, mainly focusing on legume based crop rotations in Southern and South-Western Australia and you may be able to find their recent publications easily.

Dr.Phogat,if you see literature,many times the changes in available N estimated by alkaline permanganate method are small and small changes brought by legume introduction can not be detected in total N estimated(changes may not be statistically significant ) under under Indian conditions.
